Splitting String with delimiter
提问by thehoule64
I am currently trying to split a string 1128-2so that I can have two separate values. For example, value1: 1128 and value2: 2, so that I can then use each value separately. I have tried split()but with no success. Is there a specific way Grails handles this, or a better way of doing it?
我目前正在尝试拆分一个字符串，1128-2以便我可以有两个单独的值。例如，value1: 1128 和 value2: 2，这样我就可以分别使用每个值。我试过了，split()但没有成功。Grails 是否有特定的处理方式，或者更好的处理方式？

Try:
尝试：
def (value1, value2) = '1128-2'.tokenize( '-' )

How are you calling split? It works like this:
你怎么打电话split？它是这样工作的：
def values = '1182-2'.split('-')
assert values[0] == '1182'
assert values[1] == '2'
回答by dmahapatro
def (value1, value2) = '1128-2'.split('-')should work.
def (value1, value2) = '1128-2'.split('-')应该管用。
Can anyone please try this in Groovy Console?
任何人都可以在 Groovy 控制台中尝试这个吗？
def (v, z) = '1128-2'.split('-')
assert v == '1128'
assert z == '2'

You can also do:
你也可以这样做：
Integer a = '1182-2'.split('-')[0] as Integer
Integer b = '1182-2'.split('-')[1] as Integer
//a=1182 b=2

split doesn't work that way in groovy. you have to use tokenize...
split 在 groovy 中不能那样工作。你必须使用标记化...

['org.apache.kafka:kafka_2.11','org.apache.kafka:kafka-clients'].each { i ->
def (g, m) = i.tokenize( ':' )
dep.exclude group: g , module: m
}
}
}
